7 Application filed July 11, 1901.

T0 at whom it may conccrm;

that the plate is always ready for service when the carriage is inposition to permit erasures.

Another object has been to render the scale plate more useful to theoperator than it has been heretofore.

The invention consists in the novel features of construction and thenovel combinations of parts and devices hereinafter described, and setforth in the claims.

In the accompanying drawings, forming a part of this description, Figure1 is a plan View of that part of a type-writer embodying my invention,showing the parts in their normal position. Fig. 2 is a similar viewshowing the paper-carriage tipped back and the scale-plate as turneddown below the line of writing. Fig. 3 is a vertical section on the1ine3 3 of Fig. 1, and Fig. 4 is a similar section on the line 4 4 ofFig. 2. v

In said drawings, 8 represents the type-cylinder; 9, the hammer forimpressing the pa-' per on the type; 10, the ink-ribbon;'1l 12, theribbon-spools, and 13 the ribbon-guide.

The paper-carriage frame is shown in part at 14, and it is provided withend risers 15 15 and is supported in the usual manner, one of itssupporting-rollers being shown at 16. In the risers are formed openings17, and parts of the carriage which tip backward to allow inspection ofthe writing and the makingof corrections are supported from movablebushings 18, located in the openings 17 and rigidly attached to or inone piece with swinging side frames or uprights 19 19, united at thebottom by a curved plate 20. The uprights 19 Serial No. 67,914. (Nomodel.)

are preferably provided with studs riding on the rounded tops of therisers 15, and the uprights form bearings for and support the mainpaper-feed roll.2l, the auxiliary or pressure roll 22 being supported onthe upper edge of plate 20. The frames 19 are adapted to swing backwardfrom the position of Figs. 1 and 3 to that of Figs. 2 and 4 to giveopportunity to inspect the writing or to make erasures.

I The erasure-plate is shown at 23, and it is movably attached to theuprights 19 by bending its ends at right angles, as at 24, against theouter faces of the uprights and securing such bent ends together by arod 25, passing through slots 26 in the uprights. This rod is bent, asat 27, so as to avoid interference by it with the hammer 9. The movementof the erasure-plate occurs when the movable parts of the carriage aretipped and is caused by the links 28, one at each end of the carriage,and pivotally joined at their lower ends to the risers 15 and at theirupper ends to the bent ends of the erasure-plate, as seen at 29 and 30.

NVhen tipped back, the plate moves from its normal position given atFigs. 1 and 3 to that of Figs. 2 and 4, and when tipped forward theplate returnsto itsnormal position. The plate is guided in'thesemovements by the guidescrews 31, held in ears 32011- the uprights 19 andpassing through'slots 33 in the erasureplate. The movement thus giventhe erasureplate carries it downward behind the paper and intoposition'directly back of the line being printed, and this occurs ateach tipping back of the carriage, so that if it is desired to plate itof course moves with the latter; but it can also be swung on pivots 35downward -make an erasure the plate is always ready to 7 and intoposition with its flat side parallel with and against the paper, andthis change of position, which may be made Whenever the erasure-plate isin its backward position and is indicated by dotted lines in Fig. 4 andin full lines at Fig. 2, brings the upper edge of the scale in exactcoincidence with the plane of the bottoms of the characters in the linethen being printed or for which the machine is then set. This swingingscale is a great convenience, as it enables the operator to repositionthe paper even after it has been once removed by simply pulling it up ordown until any desired line is immediately above the depressed scale, asshown at Fig. 2. It is also specially convenient when the work in handconsists in filling blanks in printed mattersuch, for instance, asdeeds, leases, &c.because by first turning the scale down on the paper,as in Fig. 2, and then moving the latter up or down until the top edgeof the scale is coincident with the bottom of the blank to be filled bythe machine the operator brings the blank into accurate alinement, andby then noting the scale-number at the initial end of the blank he isable at once by the aid of the printing-center indicator 36 to laterallyposition the carriage correctly, so that the first character struck willwith certainty fall in its proper place at the beginning of the blank.

The scale-plate returns to its normal position after being used asstated, under the power of spring 37, and a pin 38, projecting from thebent end of the erasure-plate, limits the throw of the spring. Thespring 39 is attached to a stud on one of the bushings 18 and assists inreturning the tipping portions of the carriage to and holding them innormal position.

By hinging the tipping parts of the papercarriage to open bushings 18 Iobtain room for the laterally-movable U-shaped frame of the hammermechanism shown in my application, Serial No. 6%646, filed June 15,1901.

1 claim- 1. In a type-writer,a paper-carriage adapted to tip, a movableerasure-plate mounted in said carriage, and devices adapted to autmmatically position the plate each time the carriage is tipped,substantially as specified.

2. In a type-writer, the combination with the tipping paper-carriage, ofa movable erasure-plate mounted in the carriage, and devices forpositioning the plate actuated automatically by the tipping of thecarriage, substantially as specified.

3. In a type-writer,a papencarriage adapted to be tipped away from theprinting-center, a movable erasure-plate mounted in said carriage andadapted to be positioned close behind the paper when the carriage is inits tipped position, and means, actuated by the carriage in its tippingmovement, for thus positioning the plate, substantially as speci fied.

4. The type-writer having a movable scaleplate, in combination withtipping paperholding devices, and an erasure-plate supporting the paperat the back, substantially as specified.

5. The type-Writer having embodied in its paper-carriage,tippingpaper-holding devices, in combination with a movable erasure-plate and amovable scale-plate, both supported upon said paper-holding devices,substantially as specified.

6. The typewriter having embodied in its paper-carriage,tippingpaperholding devices, in combination with a movable scale-platesupported upon said paper-holding devices and moving from its normalposition above the line of writing to a position below such linewhenever the paper-holding devices are tipped, substantially asspecified.

7. The combination of the main carriageframe and the swinging side frame19, of the erasure'plate movably mounted on said side frames and thelinks connecting the erasureplate to the main frame, substantially asspecified.
